Any organization has the responsibility of ensuring that its IT infrastructure is integrated enough to protect proprietary information. The threat of being hacked by any given third party is very real, especially because the Internet is a large pool of virtually open data for all who have access to it.
Loss of critical data or inability to control one’s equipment is the worst nightmare scenario. Should this data, if you are a government agency, fall into the hands of an unfriendly organization, it may have national security consequences. Because of market-based and other reasons mentioned, agencies and organizations are already cautious in handling proprietary information and integrating systems.
As the trend toward cloud computing continues, many questions continue to be asked about cloud security. Just how secure is “the cloud?” While it may be possible to see the economic and logistical benefits of cloud computing, no compromise is possible regarding the integral protection of valuable data. Large-scale and highly complex cryptography does exist, but is it enough? In fact, there are many ways to address security issues, which can include the role-based computing model for cloud security.
Role-based cloud security is an emerging capability that is sure to see integration at the highest levels of just about all organizations with large cloud implementations. Individuals are assigned levels of security based on their ability to access key information and the possible impact or need they have on this information.
Thus, cloud-enabled organizations can now create, manipulate, manage, route, and even report access, use, and modify data within segregated or protected resources within a private or public cloud network. It should be noted that individuals are not assigned permissions directly but only due to their role in the appropriate data. Within an organization, the definition of a cloud role is constant, yet individuals may be assigned or reassigned to the role for flexibility, enhanced security, and logistical control.

In developing protocols for cloud security, specific authentication languages, like Security Assertion Markup Language (SAML), are used for authentication levels between related domains. LDAP integration and other interrelated technologies may provide further layers of cloud security.
Integrating this protocol and extending it into a cloud scenario may define and secure an existing set of trusted user models. In short, these specialized languages, of which several are emerging, are used by cloud security service providers to develop security-focused applications that work in partnership with cloud computing providers like Amazon or Rackspace.
Cloud security specialists often have an independent credentials system that is not accessible directly on the Internet. The access portions of the security application related to key management, user accounts, or actual data are completely separate. Authentication and encryption credentials are established according to customer-specific encryption keys, never stored within the file system or otherwise accessible.
All the important keys are encrypted outside the cloud on an inaccessible server. This technology can maintain complete separation and organization, which is enough assurance that any unwanted intrusion by a third party or any tools shall not be granted to your critical data. Cloud security will continue to evolve and improve and will be the highest priority for an enterprise that places security above all else.
